OTB Hygrometer accuracy

[Life's Drives]

When you first got your hygrometer and did the salt calibration test how accurate was it Out-of-The-Box? I got a simple Radio Shack (Canadians now call it "The Source" - same crappy stuff, just a different name), I did mine and got a reading of 68%. I suspected that I had not added enough water to the salt as it was still really dry so I added exactly 3 more drops (to my tablespoon of salt) and did the test again twice. This time both results were 74%!! I am kind of surprised by a cheap Radio Shack hygrometer's accuracy so I had to ask here...??

My Radio Shack hygro (can't remember the #, but it's just a little rectangular Humidity/Temp unit) was spot on out of the box and still is 1 1/2 yrs later.

Not bad for the price I got it at with the $10 off coupon.

Probably the best cigar-related bargain I've gotten.

I have two Radio shack hyg. and both tested 75% out of the box

One of my two Radio Shack hygrometers was 2% off, the other was dead on. I will be re-doing a salt test this weekend to verify no changes for the past year.

I have three hygro's from Little Havana; two of the "Micro" size and one of the "Perfecto" size. All three, in the same bag at the same time, tested on the money @ 75%. They tell me that they do 100% QC on outgoing hygros....sure like mine.

Has anybody seen digital's change over time. In theory they shouldn't but....

Just got 2 of the "micro" sizes as well. Both tested dead on and are now in my new humidors that I got for xmas! Need another one already though! had a brain fart when I ordered them and didn't order enough. Very happy with them so far!

I like the compact size. I might order a few to update some of my current LCD hygrometers.

I was wondering the same thing. Does accuracy suffer with loss of battery life. I dont think it should but???

I have two Radio Shacks...one is +4 and the other is +2

Not sure about battery life but I replaced all the batteries in mine at the first of the year (one year old) just to be sure. L.H. sells the batteries very reasonably and as I recall the shipping was free.

Haven't tested mine since I got the "Perfecto" about six months ago. May get around to it again...truth is they seem stable as can be.

I have a western caliber 3, and it is dead on

 

[SMOKE!]

This thread got me thinking about the salt test. The thread started says hed added 3 drops of water and got a 6 point increase in humidity. How do I know I have exactly the right amount of water? I used a bottle cap from a 2 liter and enough salt to fill it. My reading came up 77. Could I have just had too much water in the salt?

I have a small digital from a few years ago, just did my salt test a few days ago and I had to do it like 3 times. Got 67 percent my first time, and I said "that can't be right"...so I did it again and added less water. Got 71 percent that time. Said doh! and added 2 drops of water and re-stirred. Got 74 percent after leaving it for 12 hours in that solution. I'm just guessing I had the right amount of water in that time, or as close as I'm gonna get anyway. But like smoke posted, I too had troubles with knowing exactly how much water to add.
